GULTIVATOR.

To all whom it may concern Be it known that 1, ROBERT C. DOUGAN, acitizen of the United States, and a resident of Millersburg, in thecounty of Holmes and State of Ohio, have invented a new and ImprovedCultivator, of which the following is a full, clear, and eXactdescription.

My invention is an improvement in cultivators, and has for its objectthe provision of a simple, inexpensive device of the characterspecified, which will thoroughly work up and disintegrate the soil, andwherein means are provided for guiding or steering the cultivator as itis drawn through the field.

In the drawings :Figure 1 is a plan view of the improvement; Fig. 2 is asection on the line 22 of Fig. 1, and Fig. 3 is a section on the line 33of Fig. 2.

In the present embodiment of the invention, a plurality of transversebars are arranged in spaced relation and substantially parallel, andeach bar is provided with teeth. The front bar 1 is provided near eachend with an arch or upwardly ofiset portion 2, and the teeth 3 areconnected with the main portions of the bar.

The second bar 4 is similar to the bar 1, having the arches or upwardlyoffset portions 5, and the teeth 3 connected with the min portions ofthe bar. The rear bar 6 is also provided with the arches 7 and with theteeth 3 and the. arches 7 are connected by a plate 8.

The plate 8 is secured at each end to an arch 7, and a stirrup hanger 9is secured to the plate 8 near each end thereof. A shaft 10 is pivotedto the under surface of each arch 7, as indicated at 11, Fig. 3, andeach shaft extends forwardly over the adjacent arches 2 and 5 of thebars 1 and 4. Each shaft is also pivoted to the adjacent arch 5, asindicated at 12, and the shafts converge slightly toward their frontends. A handle 13 is connected to the bar 4 near each of the arches 5,as indicated at 14, and on the inner side of the arch, and each handleextends rearwardly through the adjacent stirrup 9.

The handles are connected by a cross bar 15, behind the frame, the saidbar having one end pivoted to each handle, as shown at Specification ofLetters Patent.

Application filed October 9, 1911.

Patented Oct. 15, 1912. Serial No. 653,700.

16. The bars 1 and 4 are connected at their ends by straps 17, and atapproximately their centers by a strap 18, the straps 17 being pivotedto the upper faces of the bars and the strap 18 to the lower facesthereof.

The bars 4 and 6 are connected at their ends by straps 19, similar tothe straps l7, and other straps 20 connect the said bars intermediatetheir ends. The straps 20 are pivoted at their front ends on a commonbolt 21, the said bolt also connecting the strap 18 to the bar 41. Thesaid straps 20 diverge toward their rear ends, which are pivoted to thebar 6 at the adjacenthanger 9, as indicated at 22.

A pair of links 23 connect the central portion of the bar 1 to thehandles 6. Each link is pivoted to the bar 1 near an arch 2, and on theinner side thereof. The links are crossed, and the rear end of each linkis pivoted to a handle 13, near a hanger 9.

A guide runner 2-1 is arranged at each end of the frame, each runnerhaving its front end upturned, as indicated at 25, and pivotallyconnected to the bar 1, near the adjacent end. A stirrup 26 is securedto the rear end of each runner and each stirrup is secured to a hanger27 connected to the bar 6.

It will be noticed, that the front bar 1 is mounted to swing laterallyof the frame by means of the handles 13. lVhen the said handles areswung from the full to the dotted line position of Fig. 1, the links 23swing the said bar 1 in the same direction as the handles, thus changingthe position of the runners 24. When the position of the runners ischanged as mentioned, the frame is steered or guided in the direction inwhich the handles are moving. When the handles are moved laterally, asdescribed, a like result follows with respect to the shafts, on accountof the manner in which the shafts are mounted. The shafts swing on thepivots 12.

The front bar is provided at each end, and at its center withreinforcing angle plates 28, each plate having one side in front. of thebar, and the other side below the same, Figs. 1 and 2. A tooth 3 isarranged directly in front of each runner. The said tooth opens a furrowfor the runner, Figs. 1 and 2.

In operation the cultivator is drawn through the field by means of adraft animal in the shafts. The teeth 3 thoroughly work up the ground,and by swinging the handles, as indicated by dotted lines in Fig. 1, theposition of the guide runners can be changed to guide or steer the frameto one side or the other. The frame is always guided in the 7 directionin which the handles are swung.

lhe straps 20 form a brace or truss between the central bar and the rearbar, and prevent swinging of the said bars with respect to each other,so that the handles act directly on the front bar. The teeth of each barare staggered with. respect to the teeth of the other bars. The handlesare constrained to move together by the bar 15 that connects them.

It will be obvious that other draft apparatus than shafts may be used.\

I claim l. A cultivator comprising three spaced substantially paralleltransverse bars, each bar having an arch near each end, a pair of shaftsfor the frame, said shafts being arranged on each side of the center ofthe bars above the arches of the front and central bar and below thearches of the rear bar, said shafts being pivoted to the arches of therear and central bars, a pair of handles connected with the central barbetween the arches and extending rearwardly above the central portion ofthe rear bar, a plate connecting the arches of the rear bar, a stirrupon the plate for each handle, the handle passing through the stirrup, abar connecting the handles, straps connecting the ends and centralportions of the front and central bars, straps connecting the ends andcenters of the central and rear bar, a link connecting each handle withthe front bar, said links being crossed, teeth on the bars, and a runnerat each end of the frame, the front end of each runner being pivoted tothe front bar near its ends, and a hanger connecting the rear end ofeach runner to the rear bar, said runners being parallel.
